SPECIFICATION formingpart of Letters Patent N 0. 773,653, dated November 1, 1904. Application filed April 29, 1904. Serial No. 205,544. (No model.)

To (tZZ whmn it may concern:

Be it known that I, ALEXANDER LAUBSOHER, a citizen of the United States, residing at Bridgeport, in the county of Fair-field and State of Connecticut, have invented a certain new and useful Improvement in Embroider ing-Machines, of which the following is a full, clear, and exact description,

The object of this invention is to supply a sewing-machine with an attachment whereby embroidery effects may be produced in connection with the ordinary stitching operation.

The invention consists of a cord-carrier of peculiar formation and means to reciprocate it across the path of movement of the sewingneedle, wherebyan embroidery cord or thread may be placed upon the work in conjunction with the stitching, as I will proceed now more particularly to set forth and finally claim.

In the accompanying drawings, illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a rear elevation of a Wheeler & I/Vilson No. 61 high-speed sewing-machine having the attachment of this invention applied thereto. Fig. 2 is a front elevation on a larger scale. Fig. 3 is a perspective view showing the cordcarrier in its first and last positions. Fig. 4 is a similar view showing the cord-carrier in its second and fourth positions. Fig. 5 is a similar View showing the cord-carrier in its third position. Fig. 6 is a plan view of a piece of the work.

While the invention is herein shown as applied to a lock-stitch machine, it is to be understood that it is capable of other application.

The cloth-plate 1, arm 2, needle-bar 3, needle 4, presser-bar 5, presser-foot 6, feed-dog 7, needle-shaft 8, and their several operating mechanisms and complementary parts for stitching and feeding the work may be and are here shown as of usual construction, excepting that the presser-foot has applied to it a leader 9 for the embroidery-cord, as will presently appear.

10 is a bracket secured to the arm of the machine at the rear by bolts 11 and screw 12 or otherwise and supporting in bearings 13 and 14 a horizontal shaft 15. This shaft is driven from the needle-shaft 8 by suitable gearing and so as to have one revolution to two of the needle-shaft, although this proportion may be varied. The shown gearing comprises a sort of sprocket-wheel 16 on shaft and a similar wheel 17 on the needle-shaft and a connecting cord belt 18.

19 is a vertical counter-shaft arranged in bearings 20 and 21 on the front end of the bracket 10 and held in position therein by a collar 22. v

The shafts 15 and 19 are connected by miter-gears 23. The lower front end of the bracket is connected by a bracket 24, bolted to it, to a bracket 25, which is secured to the arm 2 by a pinch-joint encircling a bushing 26, through which the presser-bar passes.

The shaft l9'has fixed to it a cam The embroidery thread or cord carrier 28 is pivoted to the bracket 10 to one side of the cam 27 and has a fork 29, which straddles the cam, and from this fork an arm 30 descends, and its lower end terminates in a substantially horizontal tapered finger 31, Working in a plane above the presser-foot. This finger has a vertical eye 32 made in a bulge 33 back of its pointed or tapered tip. The embroidery cord, braid, or thread 34 is led from any suitable supply through a leader 35, under a pin 36, around a tension device 37 and a leader 38 on the overhanging arm, through the leader 9 on the presser-foot, and then through the eye 32 in the cord-carrier, as indicated in Figs. 2 and 4. The needlethread 39 is supplied to the needle in any suitable Way.

As the machine runs for operating the stitching and feeding mechanisms the cord-carrier is first brought into the position Fig. 3, needle down, and then as the needle ascends and is ready again to descend the cord-carrier is brought into the position Fig. 4, so as to present the cord to the action of the needle-thread, the bulged tip shoving the slack of the needlethread aside, as shown in Fig. 4, and as the needle is about to enter the work the cordcarrier moves into position Fig. 5, and the stitch is formed to one side of the cord. The cord having been carried to the left of the needle, Fig. 5, the next stitch is formed on the opposite side of the cord, and then the parts move into the position Fig. 4: and then into the position Fig. 3, and these successive movements follow in repetition. Hence while there is a straight line of stitches the cord is laid in a wave line and is fastened to the work by the overlying lengths of needle-thread of the several stitches, as clearly shown in Fig. 6. The cord-carrier is thus given a reciprocating movement across the line of feed of the Work at successive movements of the needle, due to the relative one to two timing of the shaft and the needle-shaft.

By the construction described an ordinary simple surface cam having a continuous rotary motion may be employed.

What I claim is- 1. In an embroidering-machine, a stitchforming mechanism including a reciprocating needle-bar, and an embroidering thread or braid carrier, the free end of said carrier formed to move the'needle-thread out of the path of the travel of said carrier, and connections between said carrier and stitch-forming mechanism independent of the needle-bar for moving the carrier in one direction at one descent of the needle and in an opposite direction at the next descent of the needle.

2. The combination in an embroidering-machine, of a stitch-forming mechanism including a needle-shaft, with an embroideringthread carrier provided at its free end with an enlarged eye portion for moving the needlethread out of the path of travel of said carrier, a cam engaging said carrier, a shaft for the cam and connections between said camshaft and the needle-shaft for moving the carrier in one direction at one descent of the needle and in an opposite direction at the next descent of the needle.

3. In an embroidering-machine, the combination with stitch-forming mechanism including a needle-shaft, of a presser-foot, a cordleader thereon, a cord-carrier independently pivoted upon the machine above said prcsserfoot and having an eye to receive the cord from said leader, and a fork next its pivotal point and means to reciprocate the said carrier across the presser-foot including a cam engaging the fork, a cam-shaft and gearing between said cam-shaft and needle-shaft.

L. In an embroidering machine, stitchforming mechanism including an overhanging arm, a bracket applied to said arm, a horizontal shaft mounted in said bracket parallel to the needle-shaft, a vertically-arranged c0unter-shaft geared to said horizontal shaft, a cam on the counter-shaft, and driving connections between the needle-shaft and horizontal shaft, combined with a cord-carrier pivoted to said bracket and having a fork embracing said cam and a depending arm terminating in a finger having a tapered tip provided with a cord-eye, and movable in one direction at one descent of the needle and in an opposite direction at the next descent of the needle.

In testimony whereof I have hereunto set my hand this 27th day of April, A. D. 1904.

ALEXANDER LAUBSCHER.
